Haifeng Automation Overall Solution for Leather Color Matching
Industry Pain Points
01
Color matching inefficiency & inaccuracy
Traditional manual color matching relies on experience, leading to color difference ≥3ΔE, frequent batch color deviation and uneven coloring; new product color matching requires repeated sampling, with a 7-10 day cycle and loss rate ≥15%, resulting in high R&D costs and slow market response, failing to meet brands’ visual consistency requirements.
02
Environmental compliance hidden risks
Partial dyes contain heavy metals and formaldehyde, with excessive VOC emissions, failing to comply with GB 18401, EU REACH and other standards, which restricts market access.
03
Poor adaptability and stability of coloring systems
Insufficient compatibility with genuine leather, PU leather and other materials causes easy fading and weak abrasion resistance; the coloring effect is highly affected by temperature and humidity, leading to limited application scenarios.
Core of the Solution
With years of experience in polyurethane equipment manufacturing, Haifeng Automation centers on “robust performance, stable quality, green compliance, and efficient mass production”. Leveraging independently developed core equipment such as automatic disc polyurethane casting machines and single/double-density molding systems, we have created a full-process solution covering material R&D, automated molding, and quality verification. This solution achieves the core goals of “wear resistance, slip resistance, environmental friendliness, and high efficiency” for shoe soles, adapts to the needs of various shoe types, and provides integrated “technology + equipment + operation and maintenance” services.
Core Solution Modules
Environmentally Friendly and Precise Color Matching System
Digital formula: Based on the CIE Lab color space, data collected by intelligent spectrophotometers combined with 5th-generation iterative color matching algorithms ensure color difference ≤1.5ΔE and batch consistency of 99.2%, certified by brands such as Anta and KUKA Home.
Customized environmentally friendly dyes: Heavy metal-free and formaldehyde-free water-based dyes paired with self-developed polyurethane-compatible additives achieve near-zero VOC emissions, complying with international environmental standards.
Multi-material adaptation: Covering a database of over 20 materials, customized solutions for different leather fiber structures avoid uneven coloring and missed dyeing.
Automated and Efficient Production System
Intelligent production line
Equipped with HF-200 precision metering color matching machines (accuracy ≤±0.1%), enabling automated proportioning, mixing and conveying. Production efficiency reaches 200㎡/hour with an annual capacity of 1.2 million㎡.
Rapid sampling and mass production
Minimum sampling volume of 0.5㎡ and cycle of 1-2 days. Formula data can be directly imported into the mass production system, reducing R&D loss to ≤3%.
